PUM P-VALVE.

SPECIFICATION forming part of Letters Patent No. 231,522, dated August24, 1880.

Application filed March 12, 1880. (No model.)

To all whom fit may concern:

Be it known that I, HENRY R. BARBER, a citizen of the United States,residing at Lambertville, in the count-y of Union and State of NewJersey, have invented new and useful Improvements in Pump-Valves, ofwhich the following is a specification.

This invention relates to valves for the barrels of ordinary lift-pumps,and has for its obi o ject to simplify the construction of such valves,to render them more effective in operation, and to impart to themdurable qualities not possessed by such valves as heretoforeconstructed.

The invention consists, essentially, in a pum-p-valve made wholly ofrubber and in a single piece, composed of a ring and a valve arrangedwithin and disconnected from the same, except at a single point, whichserves as 2o a connecting-joint by which the valve can vibrate, theupper surface of said valve being formed with an enlargement orprot-uberance serving as a weight to close the valve when raised by theaction of the pump-piston.

The invention further consists in a pumpvalve made wholly o1' rubber andin a single piece, composed of a ring, a valve arranged within anddisconnected from the same, except at a single point, which serves as acon- 3o meeting-joint by which the valve can vibrate,

an enlargement or protuberance on the upper side of the valve, servingas a weight to close the valve when raised, and an arm or leverprojecting in an upwardly-inclined direction from the protuberance orenlargement, which serves as a means to temporarily retain the valveraised from its seat, the several parts before mentioned being molded orshaped integral of rubber, whereby a cheap, durable,

4o and efficient pump-valve is provided, and one in which the weightedprotuberance and its arm or lever cannotbecome detached from the valveproper, which is very liable to occur where such weight is made of metaland connected to the valve by' a screw.

In the accompanying drawings, Figure l represents .a view of my improvedvalve applied to an ordinary pump, Fig. 2, a perspective view of myimproved valve.

5o Referring to the drawings illustrating one mode of using my valve,the letter A indicates an ordinary pump-barrel provided with the usualvalve-seat a, and B indicates a pumppiston, all of which may be of anyknown construction. y

The improved valve is composed wholly of rubber and in a single piece,and is preferably molded into shape, but it may be otherwise broughtinto the required form.

It consists of an annulus or ring, O. and a 6o disk-valve, D, arrangedwithin the ring, and disconnected therefrom by an intervening annularspace, b, except at a single point, where said valve is joined to theinner portion of the ring by a connecting-piece or narrow strip, c,which serves as ajoint by which the valve can freely vibrate.

The Lipper side or face of the disk-valve is fashioned or formed intoasemi-cylindrical protuberance or enlargement, E, from which ema- 7onates a teat, arm, or lever, F, which is located at one side of thevertical axis of the semicylindrical enlargement, and which extends inan upwardly and outwardly inclined position, so that it may be struck bythe piston when desired, for a purpose hereinafter explained. The" valvethus formed is arranged over the end of the pump-barrel, the ring Oresting on the ledge c and the disk-valve D resting on the valve-scat aof the pump-barrel. The ring 8o O is confined in place on the ledge ofthe barrel by a metallic annulus, d, suitably confined m place, all insuch manner that no water can escape between the outer edge of the rin gand the pump-cylinder.

Although I have illustrated this manner of applying my valve to apump-barrel, it is manifest that other means can be employed, as suchlform no essential feature of the invention.

The pump-piston is of any of the usual con- 9o structions, beingprovided with a suitable ball or other form of valve which will open onthe descent of the piston and close on the ascen tof the same, themovement of the disk-valve D being of course the reverse of suchmovement 95 of the piston-valve.

In case it is desirable to permit any water in the pump-cylinder abovethe disk-valve to repass into the pump-barrel below such diskvalve, inorder to avoid freezing of the water 10Q in the pump-cylimler, it isonly' necessary to force the piston down to cause it to come intocontact with the arm or lever F, which has I the ci'ect of tilting` orlifting the disk-valve l and temporarily retaining '1t in such positionuntil the water in the pump cylinder repasses I into the pump-barrelbelow the valve, a-tter. which thc pistou is slightly raised to releaseI the valve, when thc latter will by gravityclose onto its seat. f

The essential and important feature of' my l invention consists inconstructing the disk valve, the ring and its connecting-joint, and ithe protuberancc or enlargement on the side of the valve, which acts asa weight to alitomatically close the valve, Iall oi' rubber and in asingle piece, the whole being fashioned, 1nolded,or otherwise broughtinto such shape from a. single piece of rubber or from a plasticcomposition of rubber.

Heretot'ore a pump-valve has been composed of a ring and an interiordisk-valve disconl nected from the ring, exceptat a single point, whichforms the joint on which the valve vibrates; but in such the weight forclosing the valve or the arm for raising the valve by the action ot' thepiston has been made of a separate piece, which is connected to thei'ace of the interior disk of the valve by means ot' a Screw passing upthrough the latter. Such is objectionable, because the screw will tearout it' the parts are made of leather or rubber; but aside from this Iam not aware that the intci rior disk-valve has been formed with amolded upwardly-prQiectiug enlargement acting as a l weight to close thevalve and formed with a teat, arm, or lever, as in myinvention, wherebyI am enabled to produce a pump-valve of this class in a much cheapermanner than those above mentioned, and the parts cannot bedetached.

Having fully described my invention, what I claim is- 1. As an improvedarticle otl manufacture, a pump-valve formed oi' a ring and an interiordisk-valvejoincd to the ring atasingle point, and having formedintegralwith the disk-valve a molded upwardly-projecting enlargement, serving asa weight to automatically close the disk-valve, said parts being formedfrom indiarubber, all in a single piece, substantially as set i'orth.

2. A plunpvalve consisting of a ring and a disk-valve arranged withinand disconnected from the same, except at a single point, which servesas ajoint, said valve heilig' formed with a protuberance or enlargementon its side,

serving as a weight, from which cmanatcs all upwardly andoutwardlyinclined arm or lever, the said parts being formed wholly otlrubber and in a single piece, substantially as shown and described.

In testimony whereot'I have hereunto set my hand in the presence of' twosubscribing witnesses.
